Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed April 12, 1913. Serial No. 760,572.

To aZt whom it may concern Be it known that I, I-IANs I I-IANsnN, acitizen of the Danish Monarchy, and a resident of Hoboken, Hudsoncounty, New J crsey have invented certain new and useful Improvements inFlush-Valves for Water- Closets, of which the following is aspecification.

This invention relates to flush valves for water closets of the type inwhich the water closet is provided with an inside perforated waterchamber from which the water is forced out to flush the water closet.

The object of the invention is to provide a flush valve adapted to beplaced inside the water closet and so arranged that when the seat of thelatter is depressed in use the valve is opened to flush the closet.

In the accompanying drawing I have shown my invention in its preferredform of a water closet seen from the front and partly in section and thevalve mechanism inside the water closet being shown in section also.

In the drawing the reference numeral 1 designates the water closet of aconstruction known to the art and which includes a ring or water chamber2 having downwardly extending openings 8.

4 is the seat.

5 represents a water supply pipe extending upwardly from the floor onthe outside of the water closet and which pipe passes through an opening6 in the wall thereof. Inside the water closet the pipe 5 carries anipple 7 having a valve seat 8.

9 is an outlet section screwed onto the nipple and to which an outletpipe 10 is screwed. The outlet pipe connnunicates with the water chamber2 as shown.

11 is a section of pipe secured to the sec tion 9. The lower edge of thepipe 11 is hammered inwardly to form a shoulder 12 upon which rests awasher 13.

1 1 is the valve stem having a head 15 and a collar 16. Between thelatter and the washer 13 there is a spring 17.

18 is a valve adapted to be seated on the valve seat 8. The valve 18 iscarried on the stem 14 and secured by a nut 19. Normally the stem 141and with it the seat 4 are lifted by the upward pull of the spring 17 toclose the valve. lVhen in use the seat 1 is forced down upon the watercloset as shown and whereby the stem let is depressed to open the valveand the water passes from the supply pipe through the valve and into thewater chamber 2 and is discharged through the openings 3 thus flushingthe water closet. After the use the spring 17 closes the valve as willbe understood.

Changes in the construction may be made within the principle of theinvention and the scope of the appended claim.

I claim The combination with a water closet having a circular waterchamber at the top, a water supply pipe extending from the outsidevertically through the wall of the water closet to the inside thereof, anipple 7 secured to said water supply pipe and forming a valve seat, anoutlet section secured to said nipple, a connection between said outletsection and said water chamber above the said valve seat, a pipe section11 secured to said outlet section, a valve for closing said valve seatfrom below, a valve stem carrying said valve and moving vertically insaid supply pipe, a shoulder formed at the lower edge of said pipesection 11, a washer on said shouldei', a collar on said valve stem, aspring interposed between said washer and the said collar for liftingthe valve stem to close said valve, a seat for said water closet, thesaid valve stem being adapted to be depressed by the said seat to openthe said valve.
